TOOL HOLDER.

Specification of Letters Patent.

Patented Mar. 14, 1922.

Application filed August 6, 1921. `Serial No. 490,215.

To all 'whom t may concern:

Be it known that I, JOHN HUNT, a citizen of the United States, residing at Newark, in the eountyof Essex and State of New Jersey, have invented certain new and useful Improvements in Tool Holders; and Ifdo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters-of reference marked thereon, which form a part of this specification.

This invention relates, generally, to improvements in tool-holders for planing machines, lathes, and other analogous machinetools; and, the present invention has reference, more particularly, to a novel and simple construction of tool-holder of the general character hereinafter more fully'set forth, comprising a stock or shank of a low-grade steel, or other suitable metal, and a cutter of a high-grade steel, detachably connected with the said stock or shank, to permit of properly re-sliarpening of the said cutter, or

to replace a worn out cutter by a new cutter, without having to dispense with the stock or shank which is still useful, and is expensive to replace.

The present invention, therefore, has for its principal object toi-provide a novel and simply constructed tool-holder for planing machines, lathes, and the like, comprising a stock or shank of an inexpensive metal, being usually made of a low-grade steel, and a cutter detachably connected therewith, said cutter being necessarily made of an expensive metal, as a high-grade steel, all with a view of providing a tool or implement in which, primarily, a worn-eut cutter can be readily replaced by a new cutter `without having to discard'the cutter-receiving stock or shank, so as not only to reduce the cost of manufacture, but also reduce the cost of the maintenance of the ltool or implement.

`Other objects of the present invention not at this time more particularly enumerated will be clearly understood from the following detailed description of'the present invention.

Vith the various objects in view, the said invention consists, primaril in the novel tool or implement, in the orm of a toolholder for planing machines, lathes, and

. other analogous machine-tools, hereinafter s et forth; and, the 'said invention consists, furthermore, in the novel arrangements and combinations of the various Vdevices and parts, as well as in the details of the construction ofthe said parts, all of whichwill be more fully described' in the following specification, and then iinally embodied in the clauses of the claims which are appended to and which form an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure l is a side elevation, and Figures 2 and 3 are a front and rear elevation, respectively, of a tool-holder showing one embodiment of the principles of the present invention.

Figure 4 isa top-end view; and Figure a bottom-end view of the said tool-holder. Figure 6 is al transverse vertical section of the tool-holder, said section being taken on line 6 6 in said Figure 4. Y

Figure 7 is a side-elevation of the stock or shank of the tool or implement, the cutter being omitted from said view; and Figure 8 is a bottom-end view of the saine. i

Figure 9 isa side elevation, and Figure 1Q a bottom-plan view of the cutter; and Figure l1 is an end viewiof an anchor or cutter-attaching means, for securing the cutter in its operative relation to the stock 0r shank of the tool or implement. i

Similar characters of reference are veinployed in all of the said above described views, to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference-'character l indicates a complete tool or implement made according to and embodying the principles of the present invention, the same comprising a main body or shank 2, usually of rectangulaicoiiiguration, when viewed from its top-end, said'body being provided at its lower endportlon with a forwardly extending abutment, as 3, and upon its lower surface, back of said abutment, with a tool-receiving extension or projection, as 4, which as will be seen more particularly from an inspection of Figure 8 of the drawings, in its width is narrower than the width of the end of the said body or shank 2, so as to provide a pair of guide-portions 5 and 6. At its end, extending near the said abutment 3, the said extension or projection 4 is preferably made arc-shaped, as at 7. The said body or shank 2 is also provided with a tubular hole or The reference-character 9 indicates a cntter which is adapted to be used with the said body 2, said cutter comprisinga body-portion 10 formed with a sharp cutting-edge 11, and with a shoulder or oli-set 12 from which extendrearwardly a pair of arms or fingers 13 and 141-, separated by a spacel conformingto the width-of the extension or projection 4, and connectedby a curved or arcshaped portion -16 which corresponds to the arc-shaped portion 7 of the said extension or projection 4. lIt will be clearly understood from the drawings, that the said cutter may be readily slid into registration with the projection or extension d, the fingers 13 and 14 being disposed upon the guide-portions el. and 5, with the arc-shaped portion 16 Yin registration with the arc-shaped poi'- tion 7. To secure the cutter in its assembled relation to the lower end-portion ot' the body or Yshank 2, a 1fastening means is provided, said `fastening means consisting, essentially, of a rod or bar 17 provided at it lower end with a plate 18 and a pair ot marginal flanges 19, said plate being adapted to be fitted over the registering portions of the said cutter and the said extension `or projection 4:, with the said flanges 19 extending upwardly for a distance along the opposite ifa-cesof the main body or shank, as shown in Figures 1 to 5 inclusive, and the said rod or bar 17 extending upwardly into and through the previously mentioned hole or ductS, a screw-threaded end-portion 20 of said rod or bar 17 projecting beyond the npper :end-surface of the said body or shank 2,I and the various assembled parts being securely dra-wn together, so that the cutter can be safely used, byv a tightening nut 21, .or other suitable .fastening means, as willbe clearly understood from an inspection of Figure 2'ot the drawings. Y

The manner vof assembling the various parts, andthe operat-ion of' the tool or implement will Vbe readily understood from thek foregoing description and from an inspection vot the several figures ot the drawings,v

the tool or implement combining in a practical manner all of the essentials requisite for the production ot' an effective and accurate combined cutter and holder, and furthermore, by the arrangement of the retaining anchor, Aall danger of deari'angeiiient or breakage, when iii use, is reduced to a minimum, the simple arrangement of the anchor permitting the quick and easy separation of the several devices when it becomes necessary to remove the cutter, as will be clearly and combinations of the various devices and parts.l as wellY asin the details of the constructionVV of the said parts, without departing from the scope of the present invention as set forth in the foregoing specication, and as defined in the Vclauses of the claims which are appended thereto.
